The pipe elbow $($shown below$)$ rests on the ground $($i$.$e$.$ gravity works into the page$).$ The

pipe diameter is $0\mathrm{.}25m$ and the flow rate of water through the elbow is $0\mathrm{.}2\frac{m^3}{s}.$ Assume

the pipeline pressure is constant at $850$kPa $($gauge$)$ over the entire length the elbow.

Calculate the anchoring force that must be exerted on the elbow to keep it from moving.
